A list of studies that show hydroxychloroquine works if taken early

Link: Global HCQ studies. PrEP, PEP, and early treatment studies show high effectiveness, while late treatment shows mixed results

I am completely open on this topic and welcome reasoned rebuttals. My understanding is HCQ is over-the-counter in many/most countries and works well if given early or used as prophylactic.

At the link above, you can click on the studies and then find their source on the lower left of the dropdown. ABN
